第一步:路由文件的配置(对你所需要的vue文件进行保存缓存标志的添加)
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Message from '@/components/Message'
import Search from '@/components/Search'
import Home from '@/components/bottomBar/Home'
import Person from '@/components/bottomBar/Person'
import Release from '@/components/bottomBar/Release'
import Collection from '@/components/bottomBar/Collection' Vue.use(Router);
const routes =[
{
path: '/',
name: 'HelloWorld',
component: HelloWorld,
children: [
{
path:'home',
component:Home, meta: {
title: 'home',
keepAlive: true
}
},
{
path:'person',
component:Person
},
{
path:'release',
component:Release
},
{
path:'collection',
component:Collection
}
]
},
{
path:"/message",
component:Message
},
{
path:"/search",
component:Search
}
];
const router = new Router({
routes,
}); export default router
第二步:router-view的设置
<template>
<div id="index">
<keep-alive >
<router-view v-if="$route.meta.keepAlive"></router-view>
</keep-alive>
<router-view v-if="!$route.meta.keepAlive"></router-view>
<van-tabbar v-model="active">
<van-tabbar-item icon="home" to="/home">首页</van-tabbar-item>
<van-tabbar-item icon="records" to="/release">发布</van-tabbar-item>
<van-tabbar-item icon="idcard" to="/collection">收藏</van-tabbar-item>
<van-tabbar-item icon="contact" to="/person" :dot="true">个人中心</van-tabbar-item>
</van-tabbar> </div>
</template> <script>
export default {
data () {
return {
value:"",
active:
}
},
mounted(){
this.$router.push("/home")
},
methods:{ }
}
</script> <!-- Add "scoped" attribute to limit CSS to this component only -->
<style lang="less">
#index{
.van-tabbar{
height: .1rem;
border-top: 1px solid #eee;
.van-tabbar-item--active{
color: orange;
}
.van-tabbar-item__icon{
font-size: .5rem;
.van-info{
padding: .05rem .1rem;
line-height: .3rem;
right:-.1rem;
}
}
}
}
</style>
第三步:在你需要保存位置的vue文件里面进行操作
<template>
<div class="htmlGlobal">
<div id="home">
<van-row>
<van-col span="" id="message" @click.native="goToMessageHtml">
<van-icon name="chat" :class="{'dot':true}"/>
</van-col>
<van-col span="" id="search">
<van-search
placeholder="搜你感兴趣的"
v-model="value"
background="orange"
@focus="goToSearchHtml"
/>
</van-col>
<van-col span=""></van-col>
</van-row>
</div>
<div id="noticeBar">
<van-notice-bar mode="closeable"
:text=noticeValue
left-icon="http://img.yzcdn.cn/vant/volume.png"
/>
</div>
<div id="vanSwipe">
<van-swipe :autoplay="" indicator-color="orange">
<van-swipe-item></van-swipe-item>
<van-swipe-item></van-swipe-item>
<van-swipe-item></van-swipe-item>
<van-swipe-item></van-swipe-item>
</van-swipe>
</div>
<div id="vanTabs" >
<van-tabs swipeable v-model="tabActive" :class="{'fixed':fixed}">
<van-tab v-for="(item,index) in tabsArr" :title="item.name" :key="index">
</van-tab>
</van-tabs>
<ShopList :index="tabActive"></ShopList>
</div>
</div>
</template> <script> import ShopList from '../ShopList'
export default {
beforeRouteLeave(to, from, next){
this.$store.commit("set_scrollTop",this.scroll);
next();
},
activated () {
this.$nextTick(function(){
let position = this.$store.state.scrollTop; //返回页面取出来
window.scrollTo(, position); })
},
components:{
ShopList
},
data(){
return{
scroll:,
fixed:false,
value:'',
//二手物品的分类信息
tabsArr:[

tabActive:

},
methods:{
goToMessageHtml(){
this.$router.push("/message");
},
goToSearchHtml(){
this.$router.push("/search");
},
handleScroll(){
if(document.getElementById('vanTabs')){
this.scroll = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop;
var offsetTop = document.getElementById('vanTabs').offsetTop;
if (this.scroll > offsetTop) { this.fixed = true;
} else {
this.fixed = false
}
}
} }, destroyed () {
window.removeEventListener('scroll', this.handleScroll)
},
mounted(){
this.$nextTick(()=>{
window.addEventListener('scroll', this.handleScroll)
})
}
}
